Long answer
After the end of the first World War, the British Mandate was set up to establish a Jewish state in the entire province of Palestine, which at the time included not only Gaza and the West Bank but also all of Jordan. The Arabs living there revolted, as they wanted the entire area of the Middle East to themselves, and refused to accept the decision of Prince Faisal (the father of the current Saudi Arabian monarchy who was considered as the pan-Arab leader at the time) to give Palestine to the Jews. The Arabs repeatedly rioted and killed many Jews, including totally exterminating local Jews in certain areas like Hebron. In order to appease the Arabs, the British divided the land area of the Mandate, and gave more than three quarters to the Arabs and thus created Jordan. Still, the Arabs wanted more and continued to riot and kill Jews, and even conspired with Nazi Germany to exterminate all Jews in the Mandate. In response, the British put severe limitations on the number of Jews that could come to Israel, including Jewish refugees hoping to escape the Holocaust, and thus consigned many European and North African Jews to death by the hands of the Nazis. So no. The Arabs did not welcome Jews to “their” land with open arms.
